I have a Katana Artist mkii and it does sound remarkably good. Remarkable because early Boss/Roland amps didnt sound very good, that was the contrast I was trying create…old Boss. Not the newer stuff.
I bought the ReVolt based on those videos you saw, and I also thought the device sounded good there, but only the clean channel lived up to expectations in my hands on use. Actually it was really good with the boost turned on.
The crunch channel was passable and the higher gain sounds like a Soldano, a sound which I generally love but the breakup is annoying. It’s kind of fuzzy in a bad way. And backing the gain down didn’t reduce the annoyance. I even put a slightly lower gain tube in and it seemed to help but not enough. And it was a bit noisy too.
It was a short honeymoon as I recall. But for the price it isn’t a terrible tool. If you are going to use it to augment a real amp it’s good. As a standalone DI to DAW or monitors it gets outdone by a modeler in my mind.
To be fair, if I recall correctly, I bought the BlugGuitar Amp1 ME at the same time so really the ReVolt just didn’t have a chance.
That and the ReVolt was marketed with the tease that it comes with 10 DynIR’s but they meant you get Wall of Sound and those IR’s for free but the ReVolt doesn’t load them onboard, it only has a mediocre analog speaker sim. If the ReVolt could load the DynIRs and run the power amp and EQ of Wall of Sound it would be so much better. I think it was designed to be a way to expand a real amps channels more so than being a stand alone solution.
